Anar'm 99 of the bracket 97 extends rearwardly and connect'e'dthereto isan arm ,fi100b'aeted..on by .aspring 101 to. hold'the platen P in the forward'position shown inFig. 16.

,JIhe spring; 101-is extended'betweema presser foot 102 and the arm 100. The presser foot 102 engages'the ,table top-103 when the arm 87 moves dpwnwardlyto reduce .thetendency of the arm 87 to spring, which might result inchattering operation of thefplaten. Thearm 100 is .mounted on a shaftl 104 extended through the arm 105 (Fig. 1) whichginterc'onnects thearrns '87. and 79. O n the opposite endof `the shaft'104 is an arm 106 I(Fig. 6) lhavinga bifurcation 107 therein closed by af-plat'e l108. fExtended through 'the plate 108 and rne'dially through the bifurcation 107 and into the arm 106 is an adfjustingescrew '1150 that 'passes through -a-pin-11`1 mounted in the bifurcation 1507, and this alsoeirtends" into a slot 112 in the arm 113 rockably mountedon 114 are pivoted about the shaft 77, and thepivot-` al movementimparted to the arm 113 is'transmitte'd throughthe pin 111 in the slot 112 therein to thearrn- 106 andthrough the lsnaft 104 to the arm '0 to move the platen P rearwardly in equal amounts on each operation and the utility of this arrangement will be setforth hereinafter.` As best shown in Figs. 3 and 9, a gear 117-is fast on the shaft62 adjacent and inwardly of `the casting 24`.` This gear is of the intermittent type," that is, it isfprovided with sets of teeth `118 and 119, intermediateY of which are pitch-line dwells 120 and 121. Mounted on the stubshaft l22-car ried by the casting 24 is an intermittent gear 123 having sets of teeth 124 and125 thereon, inter` mediateof which are pitch-line` dwells 126` and 127. When-movement is imparted to the shaft 62 to rotate the same in a clockwise direction; the teeth 1l8'will` engage the teeth 125and rotate the gear 123 and consequently the stub.' shaft 122 until the dwell 120 engages the dwell 127'when no further movement will be imparted to the'gear 123 until the teeth 119 engage the teeth 124 at l, whichtim'e the gear `123 will again berotated substantially one-half revolution. Therefore, it is manifest that an intermittent motion. isimpartedto the shaft 122. Fast on the shaft-122 is a crank 127 (Figs. 3 and 9)" to which one end of a link 128 is pivotally connected and the opposite` end of said link is pivotally connected at 129 to a rocker 130. Theprinting devices from which the impressions are made'through a suitable inkY ribbon R by the platen P are introduced into a magazine M arranged at the rear of the machineand extended above the table-top." Ar' ranged intermediate the castings23 andf24 in alignment with the magazine M and below the table top are two castings 131 and 132 in which the printing device guideways are provided `and through" which guideways the printingdevices'v are passed in` a step-byfstep manner from the magazine through `printing' positionto a collecting galley arranged below the castings. 1 Journaled in thecastings 131 and 132 is a shaft 133 (Figs. 3, 9,2and 18) on one end of which a rocker-130 is xed. Printing devices aremovedin a step-bystep manner by carrying bars,` 136 (Figs. 11a, 14 and .18), which carrying bars are arranged inwardly of each of the castings 131 and 132. In the carrying bars 136 are slots 136' in which rollers v137' are arranged. The rollers 137"are carried by studs 138', respectively mounted in the blocks 139" (Figs. 11a, 13A and 15a) slidably mounted in slots 140 in the castings 131 and 132 and normally urged downwardly by springs 141-'. As best illustrated in Figs. 11a and 15a, the blocks 139 include ledges 142. Since the carrying bars are supported by the rollers 137', it is manifest that these bars may be reciprocated horizontal,

ly and since the blocks 139, are mounted for ver tical movement it is manifest* that a verticalV movement `may be imparted to the carrying bars., 136. Therefore, these bars may be moved in a 18, andit isthis rectangular movement thatiimparts the step-by-stepfmovement to the printing` devices. yArranged'between the castings. 131'A and 132 are castings 144 (Figs. 3 and111a)1andar' ranged betweenthese castings and the` carrying barsarelocking bars 137 (Fig. 15)` which vare thereby retained in position for Aonly vertical` movement. `These locking barsiengage-and hold the printing deviceslduring the .time the carrying bars are moving downwardly, rearwardly and upwardly, Jas previously describedwln order ,to impart an up and down :movement tothe locking bars and the J rectangular vmovement to the carrying bars,.I arrange below thesebars `so-called cam bars. Arranged below and engaging ,the locking bars 137 are cam :bars 138 (Fig. 16) and'` mounted at the endsthereof on thegsides disposedtoward the carrying bars'136 are blocks 141. Arrangedbetween the blocks 141 below 4the ledges 142 .are cam bars 142 and sincel these vbars. are mounted between the blocks 141, it is manifest thatv these' cam` bars are movable horizontally with the cam bars 138. Mounted on they castings 131'and 132 `at fspacedintervals are rollers 140 (Fig. 18)." In the cam bars `138 are cam notches or grooves 139 and arranged in the cam bars 142 are cam notches or grooves 143. l i .l

At` thewbeginning of an operation, as shown in Figx18, the` cam bars are so disposed thatthe rollers 140 'engage `thedwells in the cam grooves 139 'and these rollers also engage the lower edges ofthe` cam bars vl42adjacent the cam grooves 1443. Therf'efore,A the` locking bars 137 areheld in a downward position and the carrying bars 136 are held in van upwardposition. In the upper surface `of the." carrying `bars -136 at regularly spaced intervals-are recesses 144 and similarrecesses 145 "areprovided inthe upper surface of thelo'cking bars, 137. lThe recesses 145 are disposed at the 'dwell positions of the printing devices `Das they move` along printing device guideways provided belowl the track membersl'if` (Fig.A 11a) When the parts are in `the position illustrated in Fig. 18, the most rearward ofthe notches 144 are disposed below the lowerend of Athe 'maga` zineM and when the carrying bars .aremoved forwardlyzthe upper surfaces of the rear ends of said bars move into position-below thevfmagazine to prevent the printing devices therein from moving therefrom. :The lowermost of the printing devices inv the' magazine M are manifestly moved into the rearwardmost of the recesses 144 when these recesses are disposed therebel'ow Thus, when the shaft 122 is operated, thecrank n 'forwardly and the' printing devicelD that 4has moveddnto the rearwardmost `of` the recesses 144` will be moved forwardlytobe alignedl with" the rearwardrnost ofthe recesses 145. When the rockersj134 move forwardly" fromthefposition illustrated in Figf'18 into the)positionlillustrated in Figi 19,-movement`wil be impartedto the locking bars to move the same upwardly and to the carrying bars to move the same downwardly,v and this isF brought about by the track cam 150 (Figs. 3` and 13) fixed onthe shaft 62. When the locking bars attaintheirzupper position, the `rear ends thereof prevent the-printing devices from moving frcrnthe magazineat `the time; thercarryingzbars areA lowered.

A.'Ihereforefthe Vtapered: portions vof the-.cam grooves 139 will -engage the rollers' 140Lwhich will Acause the-.campers 138'to1be moved upwardly, :and the 'upward-.movement of`the camv bars '138i is transmitted to zthe locking bars 137 that'rrest thereon. Thus, :since the carrying bars 136 havef movedforWardly-to align 'the printing device D 'disposed inrthe rearwardmost of the recesses 144 with the `rearwardmost of the recesses 145, .this1upward1movementof the locking bars 137 'will cause this printing device lto bevenga'ge'd `:in the: rearwardmostrecesses 145.

Thus'rthe. printing devices D move onto the anvil ina-.position wellfbelow the plane of theribbonR and 1 the -1 likelihood .of these Adevices catchingzlon therribbonis therebysubstantially obviated. -The piece of work on which the impression Vis to-.be madeestsion the 'table top/and when acted `on bythe platen-is torcedtoward the printing charactersmn .the-printing device. `It is therefore advantageous -.to position the printing characters inthe. plane ofthe .tabletopso that the .piece of workfpwill needr-notbevdistorted during .the

It is sometimes desirable to make more than ing position until duplicate, triplicate,orother multiplicate operations have been made therefrom. To this end, means are provided whereby `the shaft 62, which operates the printing device feeding mechanisms, may be rendered inoperative while the platen P remains operative, and this means includes the following mechanisms: .A`

bracket 157 (Fig. 2) carries a shaft 158 on which, in the present instance, four discs 159, 160, 161, and 162 (Figs. 2 and 12) are mounted. The disc 159 isimerely a circular plate. The disc 160 is a circular plate on the periphery of which are alternately arranged lobes and depressions of equal size. The disc 161 is a circular plate having alternately arranged lobes and depressions on the periphery thereof and the lobes are twice the length ofthe depressions.` On the periphery of the circular plate 162 alternately arranged lobes and depressions are provided and the `lobes are three These circular plates 159 to 162, inclusive, provide consecutive, duplicate, triplicate, and quadruplicate impressions, respectively, and if a greater number of impressions were desired additional discs would be provided having lobes and depressions thereon suitably arranged. In the bracket 157 a shaft 163 (Figs. 2 and l2) is journaled and keyed thereto to be slidable therealong and movable therewith is a bearing164 including an arm 165 carrying a roller 166. A handle 167 on the bearing 164 facilitates sliding thereof along the shaft whereby the roller 166 may be aligned with any,

ing lobes and depressions thereon an oscillatoryJ movement is imparted to the shaft 163 in accordance with the lobe and depression arrangement on the periphery of the disc with which the roller is engaged. (Therefore, by positioning the roller in alignment with a selected disc the nature of operation of the printing device feed mechanisms is determined; that is, it is arranged to retain the printing device on the anvil for consecutive,

duplicate, or other multiplicate printing operations. This isgcontrolled by the movements imparted to the shaft 163 to which a crank 171 (Figs. 2 and 6) is secured. Pivotally mounted at 168 on the bracket 157 (Fig. 2) carried by the casting 22 is a shroud 169 and a roller 170 thereon is held against the crank 171 by the spring 178.

Thus, when the shaft 163 is moved the shroud 169 will also be moved and this shroud is movable into the path of the tail of the pawl 71. When the tail of the pawl engages the shroud, the nose 73 thereof is disengaged from the notch 74 and therefore no movement is' imparted to theshaft 62, Movement is not imparted to the shaft 163, when the roller 166 is aligned with the disc 159 and the shroud 169 is held out of theI path of the tail of the pawl 71 but when the roller 166 is aligned with a disc which has lobes thereon,

and this roller engages a lobe, the shroud is positioned in the path of the tail andtherefore on certain operations of the platenno .movement will be vimparted to the shaft 62 and thus the printing device feeding mechanism will be ren- 8O ldered inoperative and therefore the printing de" vice on the anvil will not be moved therefrom. The roller 166 is held against the disc with which it is aligned by a spring 166. In order that the shaft 168 will receivewmovement in accordance 85 with the operations of the platen, I drive the" shaft 158 carrying the discs by a pawl` 172 (Figs. 6 and 10 mounted on an arm 173 on the platen bearing 78 and this pawl is held in engagement with a ratchet 174 on the shaft 158 by a spring175. 90 Thus upon each operation of the platen, move" ment will be imparted to the shaft 158'andthis movement, as" above described, will control the operation of the printing device feeding mechanisms in accordance with the dispositionof the roller 166. j It is therefore manifest that the shaft 62 is sometimes disconnected from the mechanisms operating'the same and in order to insure that said shaft will not overrun and thus destroy the` 10U timing of the parts, a drag brake is applied there-'W' to which consists of the arms 176 and 177 (Fig. 10) carried by a plate 178 secured4 to the rail 26. 'I'hese arms are urged into gripping engagement with a collar 179, fixed on the shaft 62, by a screw 180 which may be tightened to apply proper ten-` sion through the arms 176 and 177 onto the collar`179.

Assuming that. the machine is setfor consecutive operation after a printing device has moi/edil() onto the anvil in the previously described man-"8 ner and an impression has been made4 therefrom, this printing device will be movedfrom theanvil upon the next operation of the carrying bars 186,

'this being brought'about by the engaging of 4them115 "ing ydevice will fall byits own weight onto the printing device guiding members 181 and '181' (Fig. 13) made of brous material or other material having sound deadening properties. -This125 is particularly advantageous since the printing i devices are usually metallic and if these guiding membersI are also metallic, objectionable noise results when the printing devicesfall into engagement therewith. 130 The upper edges of the guiding members 181 are shaped to direct the released printing devices to the packer member 182 pivotally mounted at 183 `and these devices are guided by this packer member into the galley G, which is in the nature 4135 yof a, removable drawer, therear end' of whichis supported by a bracket 184 (Fig. 9)v and the forward end of which is supported by a bracket`185.

A suitable manually operable latching device generally indicated by 186 is providedfor holding 140 the bracket andthe forwardend of the galley G in the upper position illustrated in Fig. 9, whereby the packer 182 will extendthereinto and thus a printing device passing over the guide members 181 to the packer `182 will be directed 145 into the galley G. `On the packer 182 there is a i stud 187 (Figs. 3 and 9) and detachably engaged therewith is a hook 188 'on the outer end of the rod 189, the other end of said rod being pivotally connected at 190 to one end of the lever 191 piv- 15o 'otally 'mounted on 'the'. casting' 132 r at`x L192. `A spring1`93` acts onthe lever I191-tourge thelink 189 forwardly.

, At the lower end of 'the frarne21 is a supporting shaft 227 (Fig. 1) onwhi'chthreeifoottpedals228, 229, and 230v are pivotally mounted. 'The lower .j .end of a rod`..231 (Figs. 1, 4, andv 5) is connected .to the'foot' pedal "229 and the upper end thereof 'is connected to a-rockeri232 fast` on the clutch shaft 50. `.Thus,'when the'foot pedal is depressed the shaft 50 is'rocked and the pin on the'arm 46 jf@ moves through the cam slot 49 to operate thearcuate arm'46'of the main clutch and, in the machine as constructed,` depression ofthe foot pedal 229 moves the' arcuate arm i from retaining.` positiontopermit' the f nose 40 tolseat in :one of the 'nisms remain operative'.

`operate the printing devicefeedng mechanism. The printing device feeding mechanism will be loperated in accordance with the disposition of the roller 166, as previously described, and therefore printing devices D will be Withdrawn'from the magazine M and fed to the anvil A.

It has been pointed out that Athe printing vdevices may be viewed prior to passa-ge thereof into printing position and it may sometimes be desirable tovmake repetitious impressions from a printing device moved onto the anvil A, and I have provided manually operable means `for vaccomplishing this. This means includes the rod 237 (Fig. 1), the lower end of which is connected to the foot pedal 228 and4 the upper end of which is connected to the arm 238 fixed on the shaft 239 `journaled in the castings 22,23, and 24. On the shaft 239`is an arm 240 (FigsQl and 8) to which a link 241 is connected, which link is `also connected to the rocker 234 (Figs. 6 and 10) pivot- ,ally mounted on the shaft 158. Thus, when the pedal 228 is depressed the shaft 239 is rocked, 'and this movement isv imparted through the arm 240 and rod 241 to the rocker 234 and this rocker moves the pawl 172 from engagement with the Aratchet 174. This interrupts movement of the shaft 158 and therefore the position of the discs thereon is not altered and thus normal automatic operation of the machine will be resumed when thefoot pedal 228 is raised. It is `also necessary thatv the printing device feed ybe interrupted when the foot pedal 228 is operated and to this end I have provided a roller 235 (Fig. 10) on the rocker 234'movablc over an arm 236 fast tothe shaftr 163 and when the rocker is moved in the manner described the shaft`163 will be moved to'position the shroud 169 in the path of the't'ail of the pawl 71`to thereby disconnect the nose 73l from the notch 74. Thus, any desired number of repeat impressions may be made froma printing device moved onto the anvil A by manipulating the foot pedal 228. o

` It is ofcourse to be understoodthat the foot pedal 229 must be held downwardly when the foot pedal 228 is operated in orderA that the machine will continue operating so that the platen will function. `However, under certain onditions'it i is desirable that the platen be rendered inoperativeand that the printing device feed mecha- To thisV end, a rod`233 (Fig. 1) is connected to the foot pedal 230 and to a rocker l242 (Fig. 10). The rocker 242 includes a hub portionhaving notches 243 therein `into which a pin 244 fast'in the shaft 50 extends. Thus,`when the rod 233 is moved downwardly by manipulation of the foot pedal 230, the pin will engage edges of the notches 243 shaft is moved due to manipulation of the `pedal229 no movement will be imparted to the rocker 242. In the periphery of the bearing portion- 78 is ainotch`245 (Figs. 6 and-10) engagepansion coupling 252. V242 is moved the rod 251 andconsequently the .abie by the hook 246 on the beu @rank `24': fast -on shaft 248. When rocker 226 is actuated by the selector *device androtates shaft 248 as described,` the hook`246 engages the shoulder 2.45 and rendersthe platen inoperative; :The bell crank 247 :has aslot 249in the arm 248 thereof in which `oneend of a rod 250 is connected. A rod 251 is connected to the rocker 242 vand the rods 250'and 251 areinterconnected by an ex- Thus, .when the. rocker rod 250 are moved, and this movement is imparted to the arm 248' of the bell crank 247 and the `hook 246 is moved upwardly to engage the shoulder 245. Since itis necessary that this operation should occur` at the start of an operation the rocker 242 is arranged on the shaft 50 in order that the ymain clutch of the machine may be controlled by the `same pedal serving to render the platenv inoperative. Thus, as long as the hook 246 engages the shoulder 245, the platen will not-be free to fall and-since the platen does ynot fall, the pad 93 will pass, butlnot engage,

the shoulder 92. It is neoessaryithat the hook 246 engage the shoulder 245 vduringsubstantially a complete operation of the machine and in order that the operator Will` neednot hold the pedal 230 downwardly I provide a'cam strip 253 on the cam 83 and I providea roller 254 on the rrocker 242. Whenthe rocker 242. is motivated and the shaft 37 is set in operationlthe roller 254 moves through the opening between theends of the cam strip 253 and engages .thesarnexand is therefore held upwardly and thus the foot pedal 230 may be released and operationof the machine will not be interrupted until the roller 254 falls from engagement with the cam strip 253.' tive -while thevprinting device feeding mechanism` remains operative 'and therefore a printing device may be passed onto and be ejectedfrom the anvil A without a printing impression being made therefrom or it may be, as termed in the art, skipped. `When a printing device is skipped by the manual means just described, it is `de- Tlius, the platen may be rendered inoperayne sirable that the numbering device `be rendered inoperative.' It has been pointed out that the bell crank 218 is securely fastened'on the shaft 248, and this is the same'shaft as that onwhichv Vprinting vdevice'moved into printing position.` I

thereforev provide aformed portion 170 (Fig. 6) on the arm 171 and by moving the. handle 167, this formed portion 170" may be engaged with the roller 170. The shape of this portion cooperates with the roller and holds the parts in position and the resulting. operation is similar to that brought about by themovernent of the rocker 234 as caused when the link 241 is moved.

Printing devices of the character used in this invention usually have a name, street address,

`and poet office `address arranged thereon invertical alignment and kin addition to this a salutation is sometimes provided on the printing de-` Thus,A the printing devices may be used vices. to address or fill in thesalutation on a letter.

`However, when the printing devicesareused vEl() or, any desired omissionzmay be made.

ner. 'the advancement of the printing devices are only purely foin-addressingpurposes,v as on envelopes, it' is desirable that the salutation be omitted. Because `of the'foregoing conditions, it is therefore desirablaunder certain .conditions that portions of the .printing devices not be. printed. Heretofore, thishas been done by'masking Vthe undesired` portions. I have, however, provided an arrangement wherebyportions ofthe printing devices may not .be printed or, as it is termed, cut oandsuch aout-off device .is clearly illustrated in Figs. .4and ,9. It has been pointed out that the spring lOlurges the arm forwardly. This is limited' by engagement of thearm 100 with the stop member 255' pivotally mounted on the platen arm 89.` The stop member 255, in the present instance,.has a polygonal periphery and the polygonal faces are spaced in different amounts from thepivotal. mounting thereof. Any one of these faces may bemoved vinto stopping relation with the.v arm to limit the forward moveyment-'thereof and by reason of the difference in centerilengths between lthe faces and the pivotal mounting ofthe stopmember, the forward position of .theplaten P may be varied. By thus determining .thexforward position of the platen P, certain of the lines of type characters on the printing devices will not be printed, or will be cut off, andin this manner the salutation sometimes provided. von theprinting `devices may bel omitted The rearward stroke of the platen P Amay be determined by adjusting. the'disposition of the bolt 111 to vary the stroke 'imparted to the arm 106 from the arm 113.

Whenthegalley is lowered in the manner previously described, an arm 186 thereon (Fig. 9) seats below'the shouldered dog-'187l fast on the 4shaft .50 'and thereby prevents movement of the shaft'50 'by manipulation of the foot pedals until the galley G..has beenrepositioned as shown in Fig. 9.

` The `printing machine herein described. embodies a'. printing device feeding mechanism which operates to advance the printing devices into printing position in a step-by-step man- The portions of this mechanism causing engaged therewith when positioned to cause advancement of the devices, for other means are provided' to. retain the printing devices during -other phases `of the operation. This mechanism therefore advances theprinting devicesl without jamming'the same andmoreover it operates to feed the printing devices in such a manner that they are .prevented` from contacting with other portions of the machine. Furthermore, I am enabled to feed the printing devices onto an anvil and then move this anvil to position the printing devices in thesame plane as the piece of work and therefore when the worlcis forced against' the printing device, to receive a printing impression, it is not distorted and therefore clear impressions may be made, which is particularly `important when 'carbon copies are being printed. Furthermore, I have provided 'a' very simple arrangement for setting the machine for automatic operation so that a printing de- 'vice may -be passed onto the anvil and ak single impression made therefrom or the machine may operate to'move a printing device onto the anvil and retain the same thereon while multiplicate impressions are made therefrom. Furthermore, I have providedr .a platen which does not receive printing'impetus until it is arranged in close juxtaposition `to the printing device from which Athe impressionis to; bemade and inzthis .manner Iprovide vasafetywhich will-obviate the likelihoodof an operator-sfingersbeing crushed. Furthermora; I1 have @embodied in the machine manually operable means which may beV employed to 'so condition `the -machine that ymultiplicate impressions may' be A made from printing devices onr the anvil and which may also-be operated to conditionpthe machine to ypass a printing device-therethrough without an im.- pression 4beingmade therefrom.
